WINDOW SHADE ADJUSTER Filed Dec.

INVENTOR Zaur 75vo2erz Patented Mar. 17, 1931 UNITED STATES cratesWINDOW-SHADE ADJUSTER Application filed December 27, 1927. Serial No.242,723.

This invention relates to a new and useful device in the nature of anadjustable shade fixture especially adapted to support a window shaderoller and to permit the shade to be adjusted vertically.

The object of the invention is to provide an adjustable shade fixture ofsimple and emcient constructon which may be manufactured and marketed ata low price.

A further object of the invention is to provide a device of the classdescribed of novel construction and arrangement of parts hereinaftermore fully described, claimed and illustrated in the accompanyingdrawing.

Fig. 1 is a front view of a window embodying my improved device.

Fig. 2 is an enlarged front elevatlonal v1ew of my improved device.

Fig. 3 is a front elevational view of the locking mechanism andoperating lever as embodied therein.

Fig. 4 is a similar view to Fig. 2 showing the corresponding pair of thedevlce.

Fig. 5 is a transverse sectional vlew taken on the line 5-5 of Fig. 3.

Fig. 6 is a similar view to Flg 5 showing another means of holding thespring.

Fig. 7 is a similar sectional v1ew taken on the line 77 of Fig. 2.

Fig. 8 is a side elevational v ew of the operating lever, per se, of thedevice.

As here embodied my improved device comprises a pair of brackets 10, orsupports,

formed from a sheet metal plate. The vertical edges of the brackets 10are formed or bent curved as at 11 and 12 so as to provide a guide, andare provided with upper and lower flanged elements 13 and 14s The shaderoller engaging member 15 1s slidably mounted in the extended portlon 16of the slide 17, and is provided with a flanged element 18, as a meansof holding the sand engaging member in position in the slide 17. Theexpansion spring 19 is adapted to engage in the engaging member 15, andis positioned in the slide 17, which is provided with a depressedportion 20, as a means of holding the spring 19 in position. The latterdescribed construction is such as will permit the engaging member 15 tobe urged outwardly as a means of retaining the tip 21 of the shaderoller 22.- Another method of holding spring 19 in position is shown inFig.6, in which the spring is held in position by an annular depressedportion 20 which engages the outside of the spring. The engaging member15 has formed therein a suitable opening 23, of a desired contour as maybe required to receive the said tip 21 of the shade roller. The extendedportion 16 of the slide 17 is provided with a raised element 16,adjacent to the periphery of the aperture formed in the said portion 16.

The slide 1'? is slidably mounted vertically in the bracket 10, and isprovided with upper and lower curved portions 24 and 25, adapted toreceive the operating lever 26, which extends vertically downwardlytherefrom through an aperture formed in the lower flanged element 14 ofthe bracket 10. The operating lever 26 is provided with a handle element27, formed or bent approximately at right angle to the main portion ofthe operating lever 26. The operating lever 26 is provided with anoffset or eccentric portion 28, positioned intermediate the abovementioned upper and lower curved portions 24 and 25 of the slidel'Z.

The brackets 10 have formed therein apertures 32 adapted to receive woodscrews or the like, as a means of securing the brackets to the innerportion 33 and 84 of the window pane 35, in proximity to the upperportion thereof.

The above described construction is such as will permit the slide 17 tobe adjusted vertically by means of the said operating lever, and whichwill permit the eccentric portion 28 of the operating lever 27 tofrictionally engage the side 12 of the bracket 10, when the handleelement 27 of the said operating lever 26 is in approximate alignmentwith the inher surfaces of the said window frame, so as to securely holdthe said slide in position.

It is obvious from the foregoing construction that the shade 22 may beadjusted vertically, so as to permit of a free passage of air from thewindow open at the top.

Having thus described my invention what I claim as new and desire tosecure by United States Letters Patent is:

l. A Window shade adjuster, comprising a member for attachment upon oneof the sideforming members of a Window frame and having guide elementsfor guiding a slide longitudinally along said side-forming'member, aslide member mounted on said guide elements and adapted for supporting aWindow shade, and a lever rotatively mounted on said slidelongitudinally of the path of motion of said slide and extending alongsaid side-forming member out of the vicinity of a shade supported'onsaid slide member and formed With an offset portion engageable againstsaid guide elements for frictionally holding the slide in adjustedpositions.

2. A Window shade adjuster, comprising a member for attachment upon oneof the side-iorming members of a Window frame and having guide elementsfor guiding a slide longitudinally along said side-forming member, aslide member mounted on said guide elements and adapted for supporting aWindow shade, and a lever rotatively mounted on said slidelongitudinally of the path of motion of said slide and extending alongsaid side-forming member out of the vicinity of a shade supported onsaid slide member, and coacting means on said lever and said member forfrictionally holding the slide in adjusted positions on said member uponslight rotation of said lever.

In testimony whereof I have aflixed my signature.
